1. Create the necessary functions to graph a Winchendon “W” (as close to the
picture below as you can get).
y=|x|
y2=2x+3
2. Label each function using function notation. [f(x)=?, g(x)=?, h(x)=?, etc. ]
f(x)=|x|
g(x)=2x+3
3. Identify the parent functions used.
I used the abs function, made x just postive, the graph will be V. The one line across the V, it is y=kx+b.
4. Explain the transformations made for each.
The W can be two parts, two V. So it is y=|x| and y=|x-5|, don't care about the across point, it is a W. For the line cross the W, it is y2=2x+3.
5. Label the domain and range of each function, notice the picture only uses parts of
lines.
y=|x| x=R
y=2x+3 x≠0
6. Finally classify each function as continuous, discontinuous, or discrete over your
specified domains.
If we just cut a part of the graph, the W should be inside of the graph. The point (2,2), we just leave the part under this point, and cut the part on the top of this point. It will be a W.
7. Include the resulting graph of your functions in your solutions with each of them
clearly labeled.
The y=|x|, and y2=|x-5|, it is parallel, and we cut the top part, whinch is on the point(2,2), it is also the crose of the two graph. Then we can see a W. If we want have a beautiful W. we can just leave the part of under(-2.2) and (7,2).
REMEMBER: Use the proper format for typing your creative assessment (problem
statement, methods, solution, generalizations, self-assessment). HINT: For
generalizations look for patterns in transformations and try to create rule(s) for the
function’s behavior.
